(1)
Integral action time 65 12 {ms} 9990
Motor stator resistance 0.00 0.00 {Ω} 64.0 Will be automatically programmed by c48
(1)
Motor rated power 0.00 {kW} 99.9 • Set to motor nameplate kW
• Lenze setting = Tmd rated kW

Motor rated speed 1390 300 {RPM} 65000 Set to motor nameplate speed
Motor rated current 0.0 0.0 {A} 480 Set to motor nameplate current
Motor rated frequency 50 10 {Hz} 999 Set to motor nameplate frequency
Motor rated voltage 0 0 {V} 600 Set to motor nameplate voltage
1
Motor cosine phi 0.80 0.40 1.00 Set to motor power factor
Note
If motor power factor is not known, use the following formulas:
cos phi = motor Watts / (motor efciency X C90 X C88 X 1.732)
cos phi = cos [ sin-1 (magnetizing current / motor current) ]
Motor stator inductance 0.0 0.0 {mH} 2000 Will be automatically programmed by c48

Drive identification • Indicates controller rating, format: xyz,
xy.z, x.yz, or x.y.z
• x. or x = voltage (2. = 200/240V, 1~;
2 = 200/240V, 3~; 4 = 400/480V, 3~)
• yz or y.z = kW rating
Examples:
2.0.3 = 200/240 V, 1~, 0.37 kW
47.5 = 400/480 V, 3~, 7.5 kW
